'Compute efficiency' and cloud computing

Cnet: Energy analogies abound with respect to cloud computing and its effect on enterprise IT operations and economics. Nick Carr's seminal work, "The Big Switch," laid out the case for why computing will be subject to many of the same forces as the electricity market was in the early 20th century. While I've pointed out the analogy isn't perfect, I will say there are often interesting parallels that are worth exploring.
